Perhaps you should try some spelling variations:
"modified invasive convolution algorithms" » "modified invasive evolution algorithm", "modified invasive solution algorithm", "modified invasive ventilation algorithms", "modified passive convolution algorithms"
"modified learning emotion algorithm" » "mobile learning emotion algorithm", "modified caging emotion algorithm", "modified learning evolution algorithm", "modified learning estimation algorithm", "modified learning predation algorithm", "modified learning method algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified invasive convolution algorithms") OR ("modified learning emotion algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified invasive convolution algorithms\") OR (\"modified learning emotion algorithm\"))".
• Removing quotes may allow a broader search: (( modified invasive convolution algorithms ) OR ( modified learning emotion algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive convolution algorithms") OR ("modified learning emotion algorithm"))*.
